I have installed freeradius via standard repositories . but I got this error message : reading pairlist file /etc/freeradius/3.0/mods-config/files/pre-proxy # Instantiating module "linelog" from file /etc/freeradius/3.0/mods-enabled/linelog # Instantiating module "log_accounting" from file /etc/freeradius/3.0/mods-enabled/linelog # Instantiating module "python" from file /etc/freeradius/3.0/mods-enabled/python Python version: 2.7.15rc1 (default, Nov 12 2018, 14:31:15) [GCC 7.3.0] python_function_load - Module 'example' not found <type 'exceptions.ImportError'> (No module named sqlite3) python_function_load - Failed to import python function 'example.instantiate' /etc/freeradius/3.0/mods-enabled/python[9]: Instantiation failed for module "python" any other library its ok -like os socket and etc - ! just have problem with sqlite3 ! there is my config files : mods-avalaible > python : python { # Path to the python modules # # Note that due to limitations on Python, this configuration # item is GLOBAL TO THE SERVER.
